Can anyone tell me what the barrel nut torque spec is for the EDgun Matador R5M? Thank you.

You need to try a couple of different settings and check the accuracy. Harmonics play a role here.

I got an answer from Brian at Edgun West he said the torque is from 10-15 Ft lbs.
The reason I asked is because I noticed when I got it the shots were pulling to the left from zeroed at 17 yards and then shooting at 50 yards it was consistently shooting left so I knew it was a barrel alignment issue. I then unscrewed the barrel nut to relieve the tension and then just snugged it down at about 10ish foot pounds. That did fix the problem I now don’t have any windage change at any range. The reason I asked what the torque spec is because when I watch the videos of the barrel installation it looks like Brian and Ed are cranking down on that nut really hard.
I hope this helps someone out because there is absolutely no information out there until now.

I was thinking the same thing. Thats a big difference there and for airgun fasteners ft lbs seems to be way to much.

I'm assuming ft lbs. There tensioned pretty tight. There threaded on both ends so should be able to take that tension. 10-15in lbs isn't much honestly

What ever it is, I think it is more important that the same torque is used every time it is taken apart. I know I have mine roughly mesmerized by feel. I can get it close, most times. A torque wrench would be a good investment just to get more consistency.

I did say foot pounds. “10-15 ft lbs” that is what Brian at Edgun west said. If it’s being questioned call or email Brian.

After some experimentation today I have been able to determine that my barrel likes to be torqued down to 20 foot pounds to achieve optimal accuracy. I tested several torque settings, just snug, 5 ft lbs, 10 ft lbs, 15 ft lbs, 20 ft lbs. (of course I used a torque wrench)
At 20 ft lbs the windage did not move when zeroed at 17 yards and then at 60 yards. At all other torques there was a change in windage at different distances. It would seem the conclusion is the barrel tension is absolutely critical to get the barrel straight. Now keep in mind this is what it took for my barrel to straighten out other barrels may be different.

I have read from other forms that the tension depending on design can change with temperature. I believe this is true for the Edgun since the barrel is steel and it is tensioned against the Shroud which is aluminum. Since aluminum expands at a greater rate than steel at higher temperatures the tension will increase and at lower temperatures the tension will decrease. Therefore you may see a change in your point of aim with extreme temperature changes.
